Includes built-in 7 inch duct adapter.

The hood or canopy size depends on the size of the kitchen. Normally a 2 to 4 burner stove/ hob requires a 2 ft chimney whereas a 3 to 5 burner require a 3 ft one. But to absorb maximum fumes or smoke, a chimney should cover the entire gas stove otherwise the heat, smoke or fumes will move out of the canopy area and cannot solve the desired purpose of a chimney.
